Product Description
This USB 2.0 Type-A female PCB connector is designed for reliable power and signal transmission in compact electronic equipment. The connector uses a PBT glass-fiber housing and a nickel-plated stainless-steel shell to deliver high mechanical strength and excellent resistance to heat and corrosion, making it suitable for long-term operation in demanding environments. Gold-flash contacts and tinned terminals ensure stable contact resistance and low electrical loss for both power and high-speed data lines.
The through-hole DIP termination provides strong solder joints on the PCB and improves retention strength compared with SMT-only solutions, especially in applications where the mated cable may be frequently plugged and unplugged. The standard 4-pin USB layout supports USB 2.0 data transmission while remaining backward-compatible with many existing cable assemblies and host interfaces.
This connector is ideal for use in power banks, smart chargers, consumer electronics, industrial controllers, communication equipment, automotive infotainment modules, and other devices that require a robust electrical connector between a USB cable and the PCB.

Precautions
Electrical rating – Do not exceed the specified current and voltage; overspec loading may cause overheating of the connector and surrounding PCB pads.
PCB layout – Follow the recommended land pattern and keep high-speed signal traces short and impedance-controlled to maintain stable transmission quality.
Soldering process – Suitable for wave-solder or selective-solder processes. Avoid excessive solder temperature or dwell time to prevent deformation of the PBT housing.
Mating compatibility – Use with standard USB Type-A male plugs and quality cables to ensure proper insertion force and contact alignment.
Mechanical stress – Avoid pulling or twisting the mated cable at extreme angles; use strain-relief structures or cable clamps in the enclosure design.
Environment – Keep away from corrosive gases, conductive dust, and condensation. For outdoor or high-humidity use, consider sealing or conformal-coating the PCB area.
